Notes on eating apples

A few days ago, the Os were eating a snack of apple slices. I had scooped out the seeds with a melon baller and left them on the side of the plate as I sliced up the apple. As they were eating, Little O decided to pick up one of the balls with the seeds in it and started to put it to his mouth. Big O stopped him and explained to him that he should not eat the apple seeds. The conversation went something along these lines:

Big O: Stop O! You don't want to eat the apple seeds. That wouldn't be good.

Little O paused, setting the little ball of apple core down.

Science Mom: It's true, O. Most people do not eat the apple seeds.

Big O: Yeah. And if you eat them, you'll have an apple plant start to grow in your belly.

Science Mom: Oh, I don't think that would actually happen. The seed would probably just leave his body in his poop.

Big O: Nope. A seed needs water and sunlight to grow and O drinks water.

Science Mom: But how would he get sunlight into his belly with the water and the apple seeds?

Big O (not missing a beat): Well, Mom, he could just open his mouth.

How does one argue with that kind of logic?!
